"informationen aktuelle" » "informationen visuelle", "annotationen aktuelle", "informationen anteil"
"informatik kulturelle" » "formate kultureller", "informatikkultur neu", "transformation kulturelle"
"informatik aktuelle" » "informatik akademie"
"informatik modell" » "information modell", "informatic model", "informatic models"

• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("informatik aktuelle") OR ("informatik modell"))) OR ("informatik kulturelle"))) OR ("informationen aktuelle")).
• Removing quotes may allow a broader search: (((((( informatik aktuelle ) or ( informatik modell ))) or ( informatik kulturelle ))) or ( informationen aktuelle )).
• Adding a wildcard symbol may retrieve word variants: (((((("informatik aktuelle") or ("informatik modell"))) or ("informatik kulturelle"))) or ("informationen aktuelle"))*.
